Answer:
(-5, 2) is the center; the radius is 2.
Step-by-step explanation:
Compare the given (x+5)2+(y-2)2=4 to:
(x+5)^2+(y-2)^2=4
(I have used the symbol " ^ " to denote exponentiation.
Now compare this result to:
(x - h)^2 + (y - k)^2 = r^2
From this comparison we see that h = -5, k = +2 and r^2 = 4.
Thus, we conclude that the center of this circle is at (h, k): (-5, 2), and that the radius is 2.
Answer:
A function is said to be an even function if its graph is symmetric with respect to the y-axis. For example, the function f graphed below is an even function. Verify this for yourself by dragging the point on the x-axis from right to left. Notice that the graph remains unchanged after a reflection across the y-axis!
with the exception of perfect squares, all square root of whole numbers are irrational, e.g. √5
how about this one:
2.34334333433334.... I am increasing the number of 3s each time, thus
creating a decimal which never ends and never repeats.
or
12.3456789101112131415.... can you see what I am doing?
will it ever end? will it ever repeat?
2x²+x-6=0
(2x-3)(x+2)=0
x=3/2 or -2
